Determine Signal Strength
Having an accurate measurement of signal strength in decibels
(dBm) is crucial when installing your system.
Decibels accurately measure the signal strength you are receiving.
(dBm) is crucial when installing your system.
Decibels accurately measure the signal strength you are receiving.
Decibels are not linear: A seemingly small increase in dBm can
make a huge difference in signal strength!
DECIBEL GAIN
